Cave surveying is usually carried out with tape, compass and clinometer.
This equipment is simple, portable and can be used in difficult situations
that would prohibit the use of more accurate instruments e.g. theodolite
and EDM based equipment. Sometimes cave surveyors make use of handheld laser
distance measuring devices and targets for improved accuracy. Handheld GPS
receivers are used to fix entrance locations so surface measurements are
seldom taken.

The final output is a large scale plan and elevation showing symbols and
notation for various types of formation, sediment, slopes, pitches, climbs,
streamways etc. 3D cave-viewing software is available for enhanced visualisation.
Measurements taken provide an essential record for future exploration and
are of sufficient accuracy to predict connections with other caves and surface
features.

Photography -

Cave photography is an acquired skill. The cave environment may be damp,
dusty or muddy. This can not only damage equipment, but may interfere
with the image quality. (Atmospheric dust and vapour often ruin flash
photographs). Controlling exposure and planning lighting requires good
communication and coordination.

We will be taking video, open shutter with bulbs, flash, slide and digital
photography. The cave images we capture, will be enhanced by shots of
the beautiful rural landscape, flora, fauna and people. These are essential
for supporting publications, articles and seminars that follow up the
trip and generate interest in the world of caving.

Exploration -

Many caves are known about and have been explored by the local population
for hundreds of years. It is sometimes surprising just how far locals
have ventured into cave systems with limited lighting, or have managed
to descend cliff-faced surface depressions. Despite this, it is still
possible to find untouched passages even in well trodden caves.
Fortunately too, there are just as many caves that are inaccessible without
the use of rope access techniques. Enormous shafts, that may be 100-450m
deep can give access to colossal stream or fossil systems for the first
time.
